Gerbera plant named ‘Garglow Imp’

ABSTRACT

A new and distinct cultivar of  Gerbera  plant named ‘Garglow Imp’, characterized by its relatively compact, broadly upright and uniformly mounding plant habit; dense and bushy appearance; numerous inflorescences with bright orange-colored ray florets; upright and strong scapes; and good garden performance.

Botanical designation: Gerbera hybrida.

Cultivar denomination: ‘GARGLOW IMP’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gerbera plant, botanically known as Gerbera hybrida and hereinafter referred to by the name ‘Garglow Imp’.

The new Gerbera plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new compact Gerbera plants with numerous inflorescences, good garden performance, frost tolerance and attractive inflorescence coloration.

The new Gerbera plant is a naturally-occurring whole plant mutation of Gerbera hybrida ‘Garglow’, not patented. The new Gerbera plant was discovered and selected by the Inventor as a single flowering plant within a population of plants of ‘Garglow’ in a controlled greenhouse environment in De Kwakel, The Netherlands in November, 2012.

Asexual reproduction of the new Gerbera plant by cuttings and by tissue culture in a controlled environment in De Kwakel, The Netherlands since November, 2012 has shown that the unique features of this new Gerbera plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Gerbera have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Garglow Imp’. These characteristics in combination distinguish ‘Garglow Imp’ as a new and distinct Gerbera plant:

-   -   1. Relatively compact, broadly upright and uniformly mounding         plant habit.     -   2. Dense and bushy appearance.     -   3. Numerous inflorescences with bright orange-colored ray         florets.     -   4. Upright and strong scapes.     -   5. Good garden performance.

Plants of the new Gerbera differ from plants of the parent, ‘Garglow’, in the following characteristics:

-   -   1. Plants of the new Gerbera are more vigorous than plants of         ‘Garglow’.     -   2. Plants of the new Gerbera have larger leaves than plants of         ‘Garglow’.     -   3. Plants of the new Gerbera have larger inflorescences than         plants of ‘Garglow’.

Plants of the new Gerbera can be compared to plants of the Gerbera hybrida ‘Garrachel’, disclosed in U.S. Plant Pat. No. 22,443. Plants of the new Gerbera differ from plants of ‘Garrachel’ in the following characteristics:

-   -   1. Plants of the new Gerbera have larger inflorescences with         longer ray florets than plants of ‘Garrachel’.     -   2. Plants of the new Gerbera and ‘Garrachel’ differ in ray         floret color as plants of ‘Garrachel’ have red-colored ray         florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Gerbera plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Gerbera plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Garglow Imp’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the autumn and winter in 15-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial Gerbera production. During the production of the plants, day and night temperatures ranged from 10° C. to 16° C. Rooted tissue-cultured plants were 25 and 26 weeks old when the description and photograph, respectively, were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 edition, except where general terms of ordinary dictionary significance are used.
